CRC Hardware with SPI and DMA

I configured a SPI transfer with DMA. 
It's working.

Now I would like to add a CRC16 at the end of the frame. I enable the CRC clock and I set the CRCEN bit.

The CRC16 is send via SPI link. But I can't check if the CRC is well done or not! Do you know what are the parameters to calculate the CRC?
-->polynom: ok
-->initial value?
-->final xor value?
--> final value inversed?

The stm used is the STM3L152.
thanks ,
